Yes they are, this will allow you to ease the top of the cover open and see the cam belt on the cam sprockets.

With this done, get some body to briefly crank the engine and check the belt turns....

Replied but post disapeared so try again.


Does anyone have a spare pair of 2.5 heads???  
Issunaz??

Is there anyone local to you who could help you to remove the cambelt cover to confirm diagnosis of snapped or stripped belt?

I am thinking that we would want to repair this in a single day, and that if the belt is broken or stripped then valves will be bent, regardless of speed at the time.  Re-valving your heads will take too long so I suggest you try to get a pair of replacement heads.
If you find some heads then I am prepared to refurbish them ready for fitting, re-lap valves, nes stem seals etc.
Then it should be a simple job of off with the old, on with the new......Ha.

OK,  Just nipped off to motorserv and am now the proud owner of some Torx sockets 8-)

Removed the two bolts and got the missus to turn over the engine, the belt is still there and turning away.

The car will not start, but there is no horrible noises when it turns over.  I presume that there is a stored error on the crankshaft timing that the ECU is preventing it from starting.

What's next?  I now have the sockets (nearly a qualified Vx mechanic ;)) !

Pete,

Thanks for the offer, if this is needed then that would be great! I wouldn't have a clue what to do with them!

Cheers

I'd be inclined to take entire cam cover off and seeing it its just slipped a tooth or 2...  ... not sure how much tolerance there is before pistons and valves have a little chat...

If I can do this with the newly acquired torx sockets, I am prepared to give it a go, but would need a bit of step by step of what is involved, preferably with pictures as I don't know the names of the parts.

Done this, the belt turns.  What's the next step?

Can you see the markings on the cam pulleys, and do they line up with marking on the backplate (might need to try to get engine to stop near TDC) - do they look more or less in line (backplate markings not hugely accurate).

There is a good 'How to' on changing cambelts on the 'Other Place' (www.vauhallownersnetwork.co.uk) which has pics and will guide you on removing the cover.

If you get the cover off then turn the crank to TDC and check the cam timing marks (this is all covered in the How to)

Check the belt for any missing teeth

Look at the tensioner assembly and the idler rollers...have the bearings broken up?

If you find anything could you post some pics?

I saw that one, no pictures :-/ not sure I could follow that.

I appreciate I am being something of a nuisance numpty with this,  I have ordered a Haynes and hopefully that will help me identify the parts referred to and let me follow this.

If there is another how2 that has numpty proof pictures please let me know.

Cheers
